1 3 rd CAMELS Meeting November 2003 Nadine Gobron & Bernard Pinty presented by Peter Cox, with no french accent The JRC contribution to CAMELS: Dataset of fAPAR products

2 3 rd CAMELS Meeting November 2003 Expected Deliverables 1.10-days composite fAPAR over some CarboEurope sites from Global monthly composite of spatially aggregated at 10 km x 10 km and 0.5 ° x 0.5° in latitude-longitude

3 3 rd CAMELS Meeting November days fAPAR over 11 CarboEurope sites from Sep to Dec This task was achieved on August 2003  fAPAR & associated products; & software to read/access products; & documentations were delivered to Galina Churkina (they should be available under the CarboData web site this month). Done Task 1

4 3 rd CAMELS Meeting November 2003 How are they organized? fAPAR time series in a 30 x 30 km window centered around the Carbodata sites IDL code to read pdf file for each site which contains … Task 1

5 3 rd CAMELS Meeting November 2003 Documentation file describes Name of Site Geographical coordinates Country Location of the Site Task 1 Ref: Gobron et. al. (2003) ‘European Vegetation Activity from Space’, CarboEurope Sites, IES, EUR EN.

6 3 rd CAMELS Meeting November days time series Monthly time series Overview of 4 Years time series Task 1

7 3 rd CAMELS Meeting November 2003 Histogram and statistics using 10-day (top) and monthly (bottom) FAPAR time series from 1998 to 2001 spatially averaged over 3 x 3 pixels over the central pixel. Task 1

8 3 rd CAMELS Meeting November 2003 At the central pixel Averaged over 3 x 3 pixels 9 x 9 pixels Single year analysis Task 1

9 3 rd CAMELS Meeting November 2003 Information associated with the spatial averaging procedure Limited variations between time-series illustrate ‘spatially homogeneous surfaces’ wrt the fAPAR product Task 1

10 3 rd CAMELS Meeting November 2003 To provide an extra piece of code to facilitate the reading of FAPAR time series when data are missing over the full window (Action on NG) Additional sites to be extracted (Action on CAMELS drivers: which sites are their highest priorities ?) 10-days fAPAR over CarboEurope sites from Sep to Dec To be Done Task 1

11 3 rd CAMELS Meeting November 2003 Global monthly composite spatially aggregated A preliminary version of the software has been developed and is currently under testing. It delivers series of products at multiple spatial resolutions, for example : 10 x 10 km & 0.5 X 0.5 degrees Task 2 Done

12 3 rd CAMELS Meeting November 2003 Contents of the file for the monthly composite spatially 0.5 x 0.5 degrees Task 2 Number of original pixels inside the aggregated one

13 3 rd CAMELS Meeting November 2003 Example of the global fAPAR monthly composite spatially 0.5° x 0.5° Task 2 June

14 3 rd CAMELS Meeting November 2003 Example (30 % reduced) of the global monthly composite spatially 10 x 10 km : fAPAR Task 2 June

15 3 rd CAMELS Meeting November 2003 Example (100%) of the global monthly composite spatially 10 x 10 km Task 2 June

16 3 rd CAMELS Meeting November 2003 Global monthly composite of spatially aggregated Task 2 To be Done Check all elements of the software (January/February 2004) Finalize the content and format of the file (require CAMELS inputs: what additional fields are useful?) Apply on Year 2001 and deliver to CAMELS for testing

17 3 rd CAMELS Meeting November 2003 What else ?? Is there any specific well-identified request from CAMELS that is not yet covered? How are we (JRC), in practice, associated to the scientific interpretation of these products ? What are the benefits of the fAPAR products and how do we evaluate them ?
